why can't import component instead of modify config

Quasar is so alwsome ! But I have some confusions on it.
For many frameworks , we can use them just “import [component name]” to reference them, why we have to modify the config file to make the components available?
And for the demos on http://quasar-framework.org/components/ , I think if we can view and modify the source code on the virtual phone it will be much nicer than going to github.
